route-eth - Adding a static route


Hi

I would like to add a static route, however I do not understand what is meant by the Address setting below

GATEWAY2=10.241.58.62
NETMASK2=255.255.255.224
ADDRESS2=10.241.57.32


Does this mean any addresses beginning with 10.241.57.32 are routed over the gateway 10.241.58.62 an address range

Thanks,

Graham

What version of linux are you using? Ubuntu? CentOS?

This will help me determine the configuration files that you are currently using.

In a debian-based environment, there is the configuration file /etc/network/interfaces.

In this case, we would typically use the following syntax:

Code:
auto eth0
   iface eth0 inet static
   address 192.168.0.100
        up route add default gw 192.168.0.1
This would specify that for eth0 the default gateway is 192.168.0.1. This would be a permanent route.

Hope this helps!!

Redhat AS 4 address field - route-eth

Hi,

I'm using Redhat AS 4 update 4 and I think I understand the reasoning behind static routes. However what I do not fully understand is the ADDRESS field.

For example the address field below, which is also reflected in netstat output. Does this mean that addresses higher than 10.241.57.32 are routed over the gateway 10.241.58.62

THANKS

Graham

@gbwien: read this post, and review the article and instructions there.

Setting up a multi-homed RHEL server with the method you're attempting does not work properly. (Been there.)

The background of that is to build a static route, where in the case above it had the same effect as typing
Code:
route add -net 10.241.57.32 netmask 255.255.255.224 gw 10.241.58.62
That depends on the specific distro, so if you have already found that info, and following the examples it doesn't work, put here the details of what you need, what you've done and what you get, and we'll try to help you.
